Quality Measures For Knee Replacement

Relieve Pain, Increase Mobility, and Improve Joint Functions

The goals of knee replacement surgery are to relieve pain, increase mobility, and improve or restore normal joint functions. Diseased or damaged parts of the thighbone, shinbone and kneecap are removed and replaced with artificial implants.

Knee replacements may be total or partial. First-time knee replacement surgery is called "primary surgery" and subsequent implant replacements are called "revisions." Knee replacements have a limited life expectancy, generally in the 10- to 12-year range, depending on the patient’s age, weight, and activity level. Partial knee replacement implants save more bone than total knee replacement procedures so future revisions can be more easily performed, if necessary.

Minimally invasive techniques can reduce blood loss during surgery, lessen pain following surgery, shorten hospital stays, reduce scar appearance and shorten recovery time. However, these procedures are not right for everybody. In particular, people who are significantly overweight, have advanced osteoporosis or severe bone deformities, or who have previously had knee surgery may not qualify. The specific surgical technique and the size of the incision will be determined by the surgeon and by the nature of the patient's joint problem and condition.

Successful outcomes for knee replacement surgery depend on several factors.

Training and experience. The Evarts Joint Center is a dedicated unit for joint replacement surgery. A multidisciplinary team of medical professionals are specially trained in, and care only for, joint replacement patients.

Expertise in procedures. All knee replacement procedures are technically demanding, but minimally invasive techniques require special dexterity and skill. Our board-certified surgeons have received extensive training and are among a select group who routinely perform both types of procedures in New York State.

Precise implant alignment and positioning. Computers can help surgeons take precise measurements to match the surface of implants to the interior surfaces of the knee. They also give surgeons greater ability to perform less invasive procedures by enhancing surgical visualization. A better fit may extend the life of a knee replacement by reducing uneven wear and increase range of motion. The Evarts Joint Center is one of the first joint centers in the country to use the evolving technology of computer assisted joint surgery.

Infection control. Infection is one of the more serious complications following knee replacement surgery but is fortunately rare. To reduce the risk, patients are given antibiotics both prior to and after surgery. Additionally, special precautions are taken in the operating room. Evarts Joint Center’s dedicated surgical suites are outfitted with ultra-clean air systems including a state-of-the art laminar air flow system and helmet exhaust systems for operating room personnel. We employ meticulous operating room discipline for skin preparation, draping, and instrument preparation.
